Risk levelMedium

0–100, higher is better. How it is calculated

The website persyn.com is currently a parked domain page managed via Sedo's domain parking service. It does not host active business content but offers the domain for sale. The site is minimalistic, primarily serving as a placeholder with advertising links and domain sale information. The technical infrastructure is basic, relying on standard HTML, CSS, and JavaScript with no advanced frameworks or CMS detected. Hosting is provided by Megazone Corp., a South Korean registrar. Security posture is limited; no DNSSEC is enabled, and no security headers are present. Privacy compliance is minimal with only a basic privacy policy linked externally and no cookie consent mechanism. Business credibility is low due to lack of contact or company information. Overall, the site functions as a domain parking page with limited user engagement or trust signals.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

8 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The domain persyn.com is positioned as a domain for sale, targeting potential buyers interested in acquiring the domain name. The business model is domain parking and resale through Sedo, a well-known domain marketplace. There are no indications of active business operations, products, or services. The target audience is general internet users or domain investors. The domain has been registered since 2002, indicating long-term ownership but no active business presence. The partnership ecosystem includes Sedo and Google advertising services. There are no subsidiaries or parent company information available.

Security posture

Security maturity is low. The domain registration status includes clientTransferProhibited, which protects against unauthorized transfers. However, DNSSEC is not enabled, which could expose the domain to DNS spoofing attacks. The website lacks security headers such as Content-Security-Policy or X-Frame-Options. SSL/TLS configuration details are not explicitly available but HTTPS is implied by the URL. No incident response or security policy information is provided. Privacy compliance is minimal, with no GDPR-specific measures evident. Overall, the site presents a low-risk profile due to its minimal functionality but lacks proactive security measures.

Recommendations

  1. Enable DNSSEC to enhance domain name system security.
  2. Implement and enforce HTTPS with a valid SSL certificate.
  3. Add standard security headers to protect against common web vulnerabilities.
  4. Provide clear and accessible privacy and cookie policies with user consent mechanisms.
  5. Include contact information and incident response channels to improve trust and compliance.

Technical notes

Notes

The website uses basic HTML5, CSS3, and JavaScript without any detected CMS or advanced frameworks. It is hosted by Megazone Corp., a South Korean registrar. Performance is moderate with no evident optimization or advanced caching. Mobile optimization and accessibility are basic, with no explicit features detected. SEO is minimal, with basic meta tags but no structured data or Open Graph tags. The site relies heavily on third-party advertising scripts from Sedo and Google. There is technical debt in the form of missing security features and lack of modern web practices.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
